Particularly, one of the characteristics of the present embodiment is that the distance between the signal wires 33s and the protection member 40 is greater than the distance between the non-signal wires 33g and the protection member 40. For example, the distance difference is at least 0.5 mm. The main function of this design is that the non-signal wire 33g is used for power transmission or grounding, and the signal wire 33s is used for high-frequency signal transmission, so as to avoid the phenomenon of spark-over (or arc) that generates point discharge during hot insertion and damages the wire or the device end parts, therefore, the above structure provides a design of contact timing difference. Furthermore, when the plug connector assembly 1 of the present embodiment is pulled out, the signal wires 33s leave the terminals (not shown) of the receptacle connector first, and the non-signal wires 33g still remain in contact with the terminals (not shown) of the receptacle connector. If there is an arc, the arc will first pass to the non-signal wire 33g, such as the ground wire, but will not pass to the signal wire 33 s.

To achieve the above-mentioned effects, a feature of the present embodiment is that each of the first and second

flat cables

30a and 30b further has a plurality of covering portions 312, and the covering portions 312 are close to the protection member 40 and correspondingly cover the plurality of signal wires 33s but not cover the non-signal wires 33g, so that the distance between the signal wires 33s and the protection member 40 is greater than the distance between the non-signal wires 33g and the protection member 40. The covering 312 may be a part of the insulating carrier layer 31 and may be formed together during an automated in-line lamination process of the flexible flat cable. However, the present invention is not limited thereto, and the covering portion 312 may be formed by covering the front end of the signal conducting wire 33s with an insulating material.
